ncoonnr nnnena- To all whom ttmay concern:

Be it known that I, WILSON BARR, a sub.- ject of the King of Great Britain, and. re.- siding at Hamilton, in thecounty of Wentworth. and Province of Ontario, Canada, have invented new and useful. Improvements in Aceount-Ledgers, of which the following is a specification. I I y invention relates to improvements in account ledgers, in ,which a plurality of trays, hinged together in a casing, and con-- are adapted to be brought from vertical to horizontal position in order to write on theleaves.

The objects ofmy invention are, first, to provide a plurality} of trays, each tray eontaining a'number of paper leaves,nesting. one in the other, therein, and adapted to be brought from and to vertical and'horizont-al position, second, to providemeans in the paper leaves to give inherent rigidity to the from one position to another position, third, to maintainthe leaves intact and in vertical position when the trays are in Vertical" po-' sition, fourth, to' 'provide means extending through the trays, to form a connect-ion be tween the'end trays, and. adapted to form a carrying connectionfor the leaves when the POSltlOIlOf thesamearebeing changed. I attain these objects by the mechanism illustrated in the accompanying drawing, in

Figure V1 is a side elevation of the device showing the same in operative position, and as'having ten trays, four of which are h'ori zontal, two vertical or' inclining rearward, and four'in a bunch, shown at an an 1e between the horizontal and the vertica only a portionofthe frame,"or'1.casing,- being shown. Fig. 2 is a face, or front elevation of one of the trays, allof which are similar, and showing three loosely connected aper leaves in the tray, the upper end part 0 said leaves being broken away, in order to show the tray, and avoid confusion in the drawing. Fig. 3 is a section of a tray through the broken horizontal line A, A, of. Fig. 2, showing three leaves therein, each leaf in single line. Any desired nun ber of leaves may be in one'tray. Fig. 4 is a similar section as in Fig. 3, showing the lower. fend I I v-Speeifieatjon of Letteris'latent. Patented Application filed ni a; "1910. seri l nas'sases;

order to escape the inner track-guides when operating the trays, that is, bringing the trays from vertical to .horizontal position,

on theintermediate trays in the end trays have long pivots as in Fig. 3,

and all the intermediatetrays haveshorter pivots as in F ig. 4. Fig. 5 is an end view of a paper lea showing corrugatedly impressed ribs or crimps at the margin thereof,

and in a single line.- Fig. 6 is an exaggerated section of a similar paper leaf, in double lines, and shown broken.

Similar letters refer to similar throughout the several views. In the drawing B, is a part of a frame- Work, orcasing, easing may beof anydesired design and construction, but must of necessity be adapted to support side track guides C and D, which extend inwardly from the casing. C and D, are shown vertical, and two guides C and D are'sh'own nearly horizontal or at an acute angle to the vertical guides. The guides 0 extend inwardly a greater distance than the guides D.- I E, are a plurality of trays, preferably of light metallic construction and are all hinged together by means of hin es having parts.

PIVOtS 2, extending sidewise therefrom. The

- place the end pivot 3, of the rear and last tray is not a hinge pivot, but is intended to support said tray when in vertical or inclining position, as shown in Fig. 1', and is longer than the intermediate pivots 2, of the intermediate trays. The pivot 3, of the first or lower horizontal tray is the same length as the supportin pivot v3, of the rear tray, which isvertica The horizontal table F, has

of an account ledger. Said pivots 4, similar to the pivots 3, and said plvots 4 are adapted to slide between the vertical guides C .and D. The vertical guides are similar to the horizontal guides- C and D. The pivots .2 of the intermediate trays are of shorter length to enable said pivots to'passout and over the inner guides D, as shown in Fig. 1, when the trays are being brought from vertical to horizontal'position, and when-this change is taking pivots 3, remain in the track, thatis, between the guides O andD, which .are'rigid with the eas ngl B. p j I The table F- rests on ro era 12, on horizons;

tal rods 13. Thelevers 14 are pivoted at 15,

and the levers 16 are pivoted at 17 to the sides of the casing. The ends of the rods 13 aresecured to the ends of the levers i l and to the bell cranks 16 respectively, a nd said levers and bell cranks are-connected together bya means of pivotal straps 18. The'opposite.

ends of the bell cranks 16 have pull springs 19, connected therewith and to the sides of the casing at 20. llhe levers and bell cranks support the table by means of the pull springs.

The table supporting mechanism is similar to the table supporting mechanism shown in my application for U. S. Letters Patent,

Serial No. 512,843, filed Aug. 14th, 1909, ac-

count registering machine.

' The track guides are of suificient length to allow the trays to be broughtto vertical, or

to horizontal position,as may be desired.

Each tray is to contain a'number of separate removable paper leaves, or sheets of paper 5, having corrugatedly impressed ribs, or crimps 6, to correspond with the ribs or .crimps 7, at or near to the margin of the trays and adapted to nest one into the other, that a large number of leaves may be employed in each tray. The crimps in the paper assist very materially in sustaining and strengthening the leaves, and keeping the same on one plane, especially so, when the trays are in vertical position, the erirnps 6 prevent the leaves from the possibility of folding or buckling, and leaving the'trays when in vertical position and also when bringing the leaves from one position to an- .other.

M are flexible rods of suitable material and form, which passgloosely' through the trays and the-leaves. One end' of the; rod is attached to the rear side of the upper and rear tray at 8, and the opposite and lower end of therod is conveniently connected to the table F, as at "9, The rod M, has an inherent nature tobend and thereby to form a quadrant at any point where the trays are brought apart from one another, as shown in Fig. 1.

When all the trays are brought to a ver- -..tical position, the table alone is inhorizontal position, and when the trays are brought to horizontal position, the rear tray, alone, remalns vertlcal. v When lowering the trays the pivots 3, of the first trayengage' with the pivots 40f the table andthereby press the table downward.

o The leaves may be brought downward one,

' or more, at a time, from the vertical forward tray, and on the rods M, and placed on the table, or from another tray, and placed on the back of the lower adjoin ng tray When horizontal that the leaf may be Written upon, and for other purposes, for instance for reference, or finding an account, the writing bemg then uppermost. The leaves are slotted on the lines 10, which ex tend from the holes through which the rods M pass, to the lower'end of the leaves, in order that the leaves may be removed from the tray.

\Vhat I claim as my invention and desire to secure by Letters Patent, is

1. In an account ledger, a casing, tracks in the inner sides thereof, a plurality of trays hinged together and pivots extending from the hinges adapted to slide in said'tracks,

flexible rods passing through the trays and connected to the last tray. a number of removable paper leaves having crnnps or ribs to stiffen the same in the tray, and supported on said rods.

2. In an account ledger, a casing, a plu-.

rality of trays hinged together and adapted to be guided from a vertical to a horizontal ribs, to stiffen the same loosely placed in the tray, means in proximity to the hinged parts thereof loosely extending through the trays and the leaves, to retain said leaves, and to allow the same to assume a position from vertical to horizontal, independently of the trays. e
